Liberty Access Technologies and WattTime partner to bring green charging to EV fleets

Smart charging technology will allow schools and workplaces to charge electric buses, vans, and more with clean energy  

Santa Barbara, CA and Oakland, CA, October 22, 2019 — Today electric fleet charging technology company Liberty Access Technologies (Liberty) and environmental tech nonprofit WattTime announced a new clean charging partnership to support schools and workplaces in their transition to all-electric fleets. WattTime’s Automated Emissions Reduction (AER) software will integrate with Liberty’s charging technology to allow buses, vans, and more to automatically charge with clean power. Liberty offers electric vehicle charging systems for the new generation of electric school buses and delivery vans. Their current clients hail from the utility space, government, the private sector, and include names such as San Diego Gas and Electric, Bristol Myers Squibb, and Los Angeles County. Expanding to support school districts’ electrification of transportation is the next step in the company’s growth. Liberty’s core offering is the HYDRA-RX AC Fast Charger Controller, which produces quick charging times at a fraction of the cost of DC Fast Chargers, enabling schools to convert more quickly to electric buses. “As firm believers in a clean mobility future, we feel it’s imperative to support schools and workplaces as they make the switch to all-electric fleets,” said Chris Outwater, CEO of Liberty. “By incorporating WattTime’s AER software with our cost-saving charging technology, we can ensure they benefit from both financial savings and carbon savings. We’re excited to help these groups reach their sustainability goals without sacrificing quality of service.” WattTime’s recently-released EV charging report—How Emissions-Optimized EV Charging Enables Cleaner Electric Vehicleshighlights just how powerful their AER-enabled smart charging can be. In the report, WattTime finds emissions-optimized EV charging can further reduce associated EV-charging emissions nearly 20 percent annually and up to 90 percent on individual days. This is above and beyond standard emissions savings that come from choosing an electric vehicle over a gas-powered alternative. “School buses and corporate fleets represent a perfect opportunity for AER to drive emissions reductions; these vehicles are only used a fraction of the day and can otherwise remain plugged in to optimize charge times for the cleanest electricity,” said Gavin McCormick, founder and executive director of WattTime. “The added bonus is that—instead of exposing schoolchildren or employees to tailpipe emissions—we’re helping make electric vehicles the norm.” Electric mobility is just one of many sectors that technology provider WattTime is involved with. Their solutions make it easy for anyone to choose clean energy and achieve emissions reductions without compromising cost and user experience. WattTime’s AER software enables smart devices of all kinds—from EV chargers to smart thermostats to water heaters—to automatically opt to use clean energy. AER monitors power generation and marginal emissions rates in real-time, then uses that data to optimize energy use based on the environmental impact of consuming electricity at a given moment. Liberty’s announcement to team up with WattTime comes soon after another partnership launched with electric company PG&E. The two will work together to support the electrification and clean energy goals of a school district in Northern California by collaborating on eco-friendly charging options for electric buses. Their pilot will be a test case for PG&E’s new FleetReady program.
